Here is my entry into this summer’s “Bandsaw Box With A Twist” contest.
A week or so ago Steve over at Mere Mortals posted a couple of Passive Amplifiers that some one had built. I really liked the idea and wanted to try something out. I looked at a number of different designs to get a good idea how they worked. I then remembered the contest and the fact they I had not made a box for it and did want to enter something. So here is the concept I cam up with. The wood although a bit plain, plays a very important part in this box. I used a chunk of Paulownia that I had. I have been playing with it recently since it is such a lightweight but heavy duty wood. now one drawback to Paulownia is that the pith dries up or just disappears. You can kind of see the void in the center of the log in pic #4. I decided to use this to my advantage though. The top is cut out so that the phone speaker rests against that hole. I then drilled my holes for the “speaker” so I broke into that hole. then using a dowel I plugged the hole up below my speaker so as to not let the send travel further down the wood.
The “speaker” and the drawer hole are both drilled out with Fostner bits. The rest of the box was shaped with the bandsaw.
Here is a short video of the amplifier in action…
The song if interested is Steve Martin’s “Clawhammer Medley”
